FREMGANGSMAADE TIL FREMSTILLING AF ISOLERINGSPLADER SAMMENSAT AF INDBYRDES FORBUNDNE STAVFORMEDE MINERALFIBERELEMENTER

摘要

A method of manufacturing insulating board elements composed of interconnected mineral fibre lamellae comprising converting a melt of mineral fibre forming starting material into fibres, supplying a binder to said fibres, causing the fibres to form a fibre web, cutting the fibre web in the longitudinal direction to form lamellae, cutting said lamellae into desired lengths, turning the lamellae 90 DEG about their longitudinal axis and bonding the fibres together to form boards, the lamellae having been subjected to a surface compression followed by a longitudinal compression either before or after the fibre web is cut into lamellae.
